PLEASE HELP!! :(
Solve the following quadratic equations. (hint: use factorization)
p^2+9p-22=0
URGENT please!!

Answer 1

p^2+11p-2p-22=0
p(p+11)-2(p+11)=0
(p+11)(p-2)=0
p=-11 or p=2

Answer 2

This one too please, the same question but,
n^2+8n+22=7

Answer 3

n^2+8n+22-7=0
n^2+8n+15=0
n^2+5n+3n+15=0
n(n+5)+3(n+5)=0
(n+3)(n+5)=0
n=-3 or n=-5

Answer 4

Thanks Thanks! :D
This one? :D
(2m+3)(4m+3)=0

Answer 5

set each factor=0
2m+3=0=>n=-3/2 or 4m+3=0=>m=-3/4

Answer 6

i dont get it! :S

Answer 7

how did you do it?
